Batteries can power anything from small sensors to large systems.While scientists are finding ways to make them smaller but even more powerful,problems can arise when these batteries are much larger and heavier than the devices themselves.University of Missouri (MU) researchers are developing a nuclear energy source that is smaller,lighter and more efficient.
"To provide enough power,we need certain methods with high energy density",said Jae Kwon,assistant professor of electrical and computer engineering at MU."The radioisotope battery can provide power density that is much higher than chemical batteries."
Kwon and his research team have been working on building a small nuclear battery,presently the size and thickness of a penny,intended to power various micro/nanoelectromechanical systems (M/NEMS).Although nuclear batteries can cause concerns,Kwon said they are safe.
"People hear the word 'nuclear' and think of something very dangerous," he said,"However,nuclear power sources have already been safely powering a variety of devices,such as pace-makers,space satellites and underwater systems."
His new idea is not only in the battery's size,but also in its semiconductor.Kwon's battery uses a liquid semiconductor rather than a solid semiconductor.
"The key part of using a radioactive battery is that when you harvest the energy,part of the radiation energy can damage the lattice structure of the solid semiconductor," Kwon said,"By using a liquid semiconductor,we believe we can minimize that problem."
Together with J.David Robertson,chemistry professor and associate director of the MU Research Reactor,Kwon is working to build and test the battery.In the future,they hope to increase the battery's power,shrink its size and try with various other materials.Kwon said that battery could be thinner than the thickness of human hair.
电池可以支持任何东西,从小型传感器到大型系统.当科学家们正在想方设法让他们规模较小但更为强大,问题可能出现在这些电池更大的要重,也超过了设备本身.密苏里大学(亩)的研究人员正在开发一种核能源更小、更轻、更高效.
“提供足够的电力,我们需要一定的方法与高能量密度”,说Jae Kwon助理电气和计算机工程教授,亩.“放射性同位素电池可以提供功率密度,远远高于化学电池.”
Kwon和他的研究小组一直致力于建立一个小型核电池,目前的大小和厚度一分钱,目的在于强化各种微/ nanoelectromechanical系统(M / NEMS).虽然核电池能引起担忧,Kwon说他们是安全的.
“人们听到那个词“核”和想到一些非常危险,”他说,“然而,核能源已经安全地驱动各种设备,例如pace-makers、空间卫星和水下系统.”
他的新想法不仅是电池的大小,还在其半导体.Kwon的电池使用液体半导体而不是固体半导体.
  “关键的一部分使用放射性电池,当你收获的能量,一部分辐射能量会损害晶格结构的固体半导体,“Kwon说,“通过使用液体半导体,我们相信我们可以最小化这个问题.”
连同j·大卫·罗伯森,化学教授和副主任亩的研究反应堆,Kwon正努力构建和测试的电池.在未来,他们希望增加电池的电力,缩小其规模和试着使用不同的其他材料.Kwon说,电池就能相对比人类头发的厚度.
